I looked into this a bit more and for example the electron mass they predict (they dont quote an error so I assume the value is supposed to be exact) is around 27 standard deviations from the measured value The prediction depends on the Gravity Constant G among other constants. AFAIK, G is has been established to only about 3 digits so far. See http://www.heim-theory.com/downloads...rmula_1989.pdf and http://www.heim-theory.com/downloads...ed_Results.pdf page 12 in particular. Also they predict a mass of an e0 ("neutral electron" apparently) at similar mass to the electron. Yet this particle has never been observed in any particle collider experiments to date. AFAIK, nobody has yet looked for a neutral electron in the predicted mass range. -- Manfred Bartz |

That means the theory is inconsistent with the data from experiments. But isn't this merely a matter of one of their input parameters having much less precision than that currently available from experimental results, which are ridiculously precise and so have ridiculously small standard deviations? IIUC, what these folks have is a theory that for the first time is spitting out results that are excellent approximations of the experimental measurements of particle masses, and doing it for the first time "from first principles". That they have to use as a starting point physical constants (IIRC, it's the "gravity one") less precise than the known values of what they are trying to predict will certainly produce results less accurate than the measured ones, the important thing is that they are producing those results _at all_; not meeting current known precisions in the predicted values isn't a useful criticism of the theory, merely a motivation to measure that one input parameter (or perhaps all of the input parameters) to precision equal to the precision desired in the outputs, _then_ see how the output accuracy is. Well who knows since they dont quote their theoretical values with any error. Given this I can only assume they are claiming the theoretical error is so small when quoting to however many significant digits they use the error is zero. In this case the quoted error is not compatible with the current world average from the PDG group at Berkeley. If they quote an error and it the measured value falls within one or 2 standard deviations of this then that is a different matter. xanthian. -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG |

If it was weakly interacting to the extent it would not have interacted
with a particle detector then it would have been seen by now by virtue of one of many analyses searching for "missing energy" in the detector. Apparently OPAL searched for this type of effect and didnt find it (according to wikipedia). I found the paper he http://www.slac.stanford.edu/spires/...WW&SEQUENCE = I suspect there will be other analyses that have been done that rely on missing energy would also be sensitive to production of such a particle. Really the onus is on the heim-theorists to tell people specifically how to search for a neutral electron type particle and to explain why it wouldnt have been seen already in analyses done, given it has such a low mass (0.5 MeV). Yes, the Higgs boson has not been observed. Neither has supersymmetry. But they do have reasons why we would not have seen them to date in the theories and they can be tested soon so we can rule them out or incorpate them into current theories. In the case of the Higgs the theory assumes the mass is sufficiently lareg we could not have seen it with the "low" energy experiments we have used so far. But the heim neutral electron has a very low mass, which is why lots of people are saying it would have already been seen. The key points (to my mind) for heim-theory is really it must make specific predictions that can be tested, it must be consistent with all experiments performed to date (which means they need to calculate errors on the predicted masses so we can see the precision they can calculate them). Also why dont they show the quark masses in their table? I needs to have all the particles we know about, because if the calculation fails for even one particle then the theory does not work as it is. The measured value is from the PDG group and is usually constructed from all available measurements to date (but not always). |

Forgive my lack of familiarity with the neutral electron prediction,
but does it mean that Heim's theory predicts a particle with the same mass as the electron, but having no charge? Hmm, but where would such a particle reside? Certainly not going to be orbiting the nucleus, if it has no charge. Nor would it have a strong force interaction to trap it in the nucleus. Perhaps the neutral electron prediction is just some 'trivial solution' which is just a manifestation of something else, as you say. |

Interesting -- how would one even look for a neutral electron? A
neutrino-style detector? Could the e0 actually be the neutrino? After all, neutrinos are neutral, and have been found to have slight mass. Could the neutrino be the "neutral electron"? Does Heim's theory predict the existence of a separate neutrino particle, distinct from the neutral electron? |

Most subatomic sized particles do not live inside atoms...so there is
no reason a neutral electron would need to for it to exist. Yes, you would look for it in a similar way to that which a neutrino is detected. The electron neutrino has too small a mass to be the neutral electron in their theory (and anyway they also list the electron neutrino in the table I think). |
